5. Includes one analog transducer input channel and one digital transducer input channel. It measures travel, penetration, rebound, overshoot time, overshoot, and switchgear operating speed using resistive and digital transducers.

6. Digital transducers accurately measure the rotation angle of single-turn or multi-turn operating mechanisms, with a measurement resolution up to 0.05°, supporting accurate assessment of whether the switch operates correctly.

7. Supports control modes: Closing, Opening, O-C-O, C-O, and O-C.

8. Capable of testing the mechanical characteristics of manually operated circuit breakers.

9. Supports editing and storing 50 switch models with customized speed definitions.

10. Supports speed-definition modification and data recalculation after test completion.

11. Built-in high-power adjustable DC power supply, equipped with a manual voltage adjustment knob, a closing button, and an opening button. This enables rapid closing/opening operation and operating voltage testing.

12. The built-in continuously output DC power supply is used for motor energy storage.

13. Supports motor current measurement. By analyzing the motor current of circuit breakers or isolating switches, it can identify abnormal conditions in the circuit breaker energy storage system or isolating switch operating system.

14. Output control uses electronic switches, providing high control accuracy and long service life.

15. Built-in current sensors measure the current of the closing coil and the opening coil.

16. Stores 500 sets of test data with power-off protection (no data loss after a power failure).

17. Export stored test data via USB flash drive.

18. Supports internal instrument software upgrades via USB flash drive.

19. Equipped with an LCD screen that clearly displays the operating interface, test data, contact waveforms, travel curves, and current curves for both indoor and outdoor use.

21. Includes a high-speed thermal printer to output test data, contact waveforms, travel curves, and current curves.

22. Supports up to 10,000 automatic operation tests.

23. Supports computer connection and operation via USB communication cable.

24. Test data can be opened on a computer for analysis, envelope generation, and report generation.

25. Reserved communication interfaces support optional external modules, including dynamic resistance measurement, double-side grounding tests, and graphite contact tests.

26. Supports online testing and internal test data extraction via Bluetooth 2.0 or above devices (optional).
